This was not at all what I expected, i.e. a thriller about some group that was exerting control to some esoteric purpose. Instead, it is a kind of metaphysical thriller, where a talented young politician doesn't fit with the plan and fights very hard to go his own way. It is a nice twist on a totalitarianism that is adaptable and not all that bad in intent, however messy the details are.
On the positive side, the chemistry between Damon (an absolutely first rate actor) and Emily Blunt is amazingly believable. They are riveting on screen, genuinely moving, at least to me. This is one level of the film, a kind of love story against all odds - how can they make it work when everything conspires against them.
So, without playing the spoiler, Damon discovers that he is being "managed", indeed that he has a destiny. He is a remarkable young politician, somewhat rebellious but committed to changing things. He has always felt a certain emptiness, an emotional hole within himself that he is attempting to fill with the "people's love" as he climbs the political ladder. Then, he has a chance meeting with an extraordinary young woman, and enters an adventure that is as indescribable as it is complex and ultimately impossible to limn. He feels fulfilled, which violates the logic of his destiny. Any means will be employed to correct things.
This is a fun film experience, but I don't want to purchase the film, because once you figure out what is happening, you get and won't want to re-experience it. Recommended.
